2. Set up grill for direct grilling and preheat to high. Brush grate with a stiff wire brush and oil with a tightly folded paper towel dipped in a small bowl of Crisco Vegetable Oil. (Hold the oiled towel with tongs and run it across the bars of the grate.) Or remove grate with heatproof gloves, and away from the fire, spray grate with Crisco No-stick Cooking Spray. Return grate to grill. Do not spray oil directly at the fire.
